AUTOMOBILE TURN-TABLE.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed April 12, 1909. Serial No. 489,522.

To all whom it may concern Be it known that I, WILLIAM T. (oLEM-AN, a citizen of the United States, and resident of Seattle, in the county of King and State of VVashin ton, have invented certain new and useful niprovements in,Autoinobile Turn- Tables, of which the following is a full, exact, and complete specification.

' My invention relates to turn-tables for use in gara es for turning automobiles, and

has for its o ject the provision of a structure consisting of metallic beams and plates having runways for the wheels of the vehicle and provided With a lug or projection in its center to seat in a socket in a plate to be secured to the Hoor of the garage, or in a socket in the top of a pillar secured to the bottom of a pit when desired, and having rollers on their journals arranged radially of the circle described by the table in turning.

The construction of my improved turnn table will be described in detall hereinafter and illustrated in the accompanying drawin s, in whichlgure 1 is a top plan view of m improved device; Fig. 2 a longitudinalY sectional view; Fig. 3, transverse section View; and Fig. 4 a view of the illar used when a pit is provided for the tab e.

In the drawings similar reference characters indicate corresponding parts in the several views.

The side sills of my improved turntable are constructed of angle-beams 1 and have I-cross-beams 2 secured adjacent to the ends thereof and with their bases extended at each end beyond the sills, as shown at 3, and compound angle cross-beams 4 secured at each side of the middle of the sills with their bases also extended, as shown at 5. The runways are secured on-v the outside of the sills and tops of the extended ends of 3 and 5 of the cross-beams',` and consist of an lebeams 6, with the vertical side 7 secure to the sills and the horizontal portion 8 extending laterally therefrom to iorrn the runway for the Wheels of the vehicle.

9 indicates brace-plates secured to each end of I-beams 2 and sill 1, and 10 other brace-beams or plates secured at each end of the compound angle-beams 4 and sill 1, this structure forming a substantial and rigid structure that has sufficient strength to support the vehicle and withstand the wrench ing incide-nt to turning While supporting the vehicle. y

12 indicates a plate secured under the top flange of com ound angle-beams 4 and having the inidd e of its under side [ornicd with circular lug or projecion 13 and the surface adjacent to the lug beveled upwardly as shown at 14.

15 indicates a hole through the center of plate 12 and lug 13, through Which to lubricate the bearing formed by the lug and the socket to be hereinafter described.

When ,the turn-table is to be installed on the floor of the garage a plate 16 is secured to the floor, said late being provided with 'a central boss 17, aving a socket 18 therein to receive the lug 13 in the center of the turn-table and forming the bearing for the center of the table.

19 indicates rollers journaled on bearin fs 20, adjacent to the inner sides of 4the ends of sills 1, the axles of said -rollers beingon planes forming radii concentric with the center of lug 13, it being understood that said rollers by having their bearing surfaces below the plane of the underside of the turntable operate to hold the table above the loor so that the movement of the table in turning is relieved of friction between -the floor and the bottom of the table.

When my table is installed in a pit a pillar 21 is secured in the center of the pit, said pillar bein provided vyith a socket 22 to receive the ug 13 and the rollers 19 may' be arran ed to travel on a circular shelf around the edge oi' the pit or a circular traclr may be provided forl the rollers, this structure being common in`- turn-tables for locomotives, etc., now-in general use and considered to be unnecessary to be shown.

Having thus described my invention, what I claim isl.` A turn-table for automobiles consisting of a frame having side sills of anule-beams, cross-beams connecting said si ls, anglebeanis secured to the outer sides of said sills and having their horizontal ortions forming runways for the vehicles w ieels, a plate. secured to the center of the frame having a downwardly-extending lug, a support for the center of the frame having a socket to receive the luv, and rollers journaled adja-4 cent to the en s of the sills and having their axes on planes forming radii concentric with the center of the'lug, substantially es shown and described.

2. A turn-trible for mitonlobilee comprising :i inline lutving side sills 0l angle-beams, cross-inmune of I-benln ty )e secured adjacent to the ends ol' the sills and having their bases extended beyond said sills, other crossbeams ol'4 compound angle-beam type seenred at euch side of the middle of the sills and having their bases extended beyond the sills, angledne:uns secured on the outside oi' the sills and on top of the extended ends of the bases of the cross-beams, the horizontal ortion of the last-mentioned angle-beams orlning runways, a plate secured to the middle of the compound migldbmnne, n hn; extendirwr dowliwaidly from the fix-rid philo and formlng the center of the freine, :t pluto having a central bees with a socket therein t0 receive said lng, and rollers join-nailed adjacent to the ends oi' the sills :md havingr their axes on planes forming radii mnwnti'iv with the center oi' the lug aforesaid, sub Stantiztlly as shown and described.

In Witness whereof, I have hereunto set my hand in presence ol' two subscribing \\'1tnesses.
